• Answer:

  No need to open anything. Some amps have high-level inputs that you tap from the speaker wires either at the HU or at the speakers themselves. Your system won't mean squat without a well designed box to put your subs in. Some manufacturers have recommendations as to dimensions of various types of boxes. It is best to find someone who builds boxes if you go with something other than a sealed box. You should always match up RMS (Root Mean Square) watts of Subs and amp per channel as well as impedance's(resistances). When a sub has rating of 600 Watts MAX it really has an RMS rating of about 200 Watts RMS. RMS is the nominal wattage your most likely going to get out of it. Remember, a 200 Watts RMS amplifier pushes more power output than a 200 Watt MAX amp. Look for subs with a sensitivity of 91 dB or higher and CEA-2006 compliant amplifiers.
